Patented July 4, 1933 I HENRY WILLIAM NAGEL, OF CHICAGO, ILLINOIS This invention relates to certain novel improvements in window structures, and has for its principal object the provision of an improved construction of this character which will be highly eflicient in use and economical in manufacture.

Among the objects of this invention are: to provide'an improved all-metal weatherproof window construction; to provide an 1 improved all-metal window construction that has no parts such as stop strips to warp or get out of alignment; to provide a window construction which includes slidable sashes counterbalanced by each other; to construct 1% the window structure so that either the upper or lower sashes may be pivoted inwardly to clean the same or for any other purpose, while at the same time the other sash is counterbalanced and held in position by the sash which is pivoted inwardly; to construct the window so that access may be readily had to means provided for adjusting the tension of the sash or counterbalance cables; and to construct the window so that water formed by condensation on the inner sides of the sashes may readily drain to the outside of the window.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by referrence to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is an elevational view of the invention as seen from the inside of the window; Fig. 2 is a vertical sectional view on line 2-2 in Fig. 1;

Fig. 3 is a horizontal sectional view on line 3-3 in Fig. 1; I

' Fig. 4 is a fragmentary vertical sectional view showing lower' sash pivoted inwardly; Fig. 5 is a vertical sectional view online 55 in Fig. 2;

Fig. 6 is a vertical sectional view on line 6-6 in Fig. 5;

Fig. 7 is a fragmentary perspective view 50 of the frame;

other arms 29 of the L-shaped stiles 15 ride Fig. 8 is a perspective view of the sash cable tensionin g turnbuckles; and Fig. 9 is a perspective view of the combination latch, bolt and sash pivot members.

In the drawings 10 indicates a wall having 65 an opening within which my improved allmetal window structure, generally indicated at 11, is arranged. Said window structure 11 comprises an all-metal frame 12 which includes a pair of similar all-metal jambs within which the upper and lower sashes 13 and 14 are slidably arranged. The upper sash 13 comprises a pair of substantially L- shaped vertical stiles 15, and top and bottom rails 16 and 17. Extending about the inner sides of the stiles 15 and the top and bottom rails 16 and 17 is a pair of spaced internal marginal ribs 18 and ,19 which provide a marginal groove for the reception of the marginal edges of the transparent pane 20 of the upper sash 13. The lower sash 14 comprises a pair of L-shaped vertical stiles 21, similar to stiles 15, and top and bottom rails 22 and 23, and extending about the inner sides of the stiles 21 and the top and bottom rails 22 and 23 of the lower sash 14 is a pair of spaced internal marginal ribs 24 and 25 which provide a groove for the reception of the marginal edges of the transparent pane '26 of the lower sash.

As shown in Fig. 3, each of the jambs 45 is provided with an interlocking groove 27 and slidable in these grooves 27 are portions of arms 28 of the L-shaped stiles 15. The

against port-ions 30 of the jambs 45.

Those portions of the jambs 45. in which the stiles 21 of the lower sash 14 are slidable are offset laterally from the portions of the jambs 45 in which the stiles 15 of the upper sash '13 are slidable, so that both upper and lower sash may be pivoted inwardly, as will appear hereinafter. Each of the jambsfi45 is provided with a verticalgroove 31. Slidably g5 interlocked in these grooves 31 are portions of the arms 32 of the stiles 21; the other arms 33 of the stiles 21 riding against portions34 of the jambs 45.

Provided in each of the portions 30 of the jambs 45 is a vertical groove 35 and provided sash, and to each of the slidable sash pivot members 37 on the lower rail 17 of the upper sash, is a turnbuckle 40 which includes an adjustable threaded member 41. Having their ends attached to these adjustable turnbuckle elements 40 and extended over pulleys or sheaves 42 that are arranged on brackets 46 in boxes 44 at the top of the window frame 12, are flexible elements or sash cables 42, whereby the upper and lower sashes are counterbalanced by each other. These cables.

42 work through holes 47 provided in the top 48 of the frame 12.

At their lower ends each of the vertical amb grooves 35 is provided with a mouth 49 formed in the frame12, and each of the grooves 36 has a similar mouth 5O; the sash pivot members 37 being adapted to enter into the vertical grooves 35. and 36 and taken out of the same through these mouths 49 and 50 1n placing the sashes inand removing the same from the frame 12. Also at the lower end of each vertical jamb groove 35 is a recess 51 formed in the frame 12, and at the lower end of each vertical jamb groove 36 .is

. a recess 52.

To pivot the upper sash 13 inwardly (Fig.' 6) so as to clean the same, to place a screen,

or for any other reason, the upper sash 13 is lowered toward the frame sill 56, into the a position of Fig. 6, and the inner ends of the sash pivot members 37 that are carried by the lower rail 17 of the upper sash 13 are projected into the recesses 51 at the bottoms of the vertical jamb grooves 35, and the members 37 on the upper rail 16 of the sash 14 are retracted out of the slots 35, whereby the thus projected sash pivot members 37 on the bottom rail 17 of the upper sash act as pivots upon which the upper sash 13 may be pivoted inwardly, Fig. 6; while at the same time the lower sash 14 is held up or counterbalanced in the position of Fig. 6, by the upper sash 13 and sash cables 42. v

a I So that the top rail 16 of upper sash 1-3 1 may clear the bottom rail 23 of the lower sash 14 and thus permit the upper sash 13 to be pivoted inwardly, as in Fig. 6, the bottom surface of that portion 53 of the top 48 of the frame 12 against which the top rail 22 of the lower sash 14 is adapted to abut when the lower sash is raised, is oifset from horizontal alignment with and is arranged slightly above the bottom. surface of the portion 54 of the frame top 48against which the top rail 16 of the upper sash 13 is adapted to abut when raised.

To pivot the lower sash inwardly, the same is pulled down and the inner ends of the sash pivot members 37 that are carried by the bottom rail 23 of the lower sash 14 are projected into the recesses 52, and the members 37 on the to rail 22 of the lower sash are retracted out o the rooves 36, whereby the said pivot memberst us projected act as pivots upon which the lower sash may be pivoted inwardly; the upper sash 13 then being retained in raised position by the lower sash and the sash collar 42.

To adjust the tension of the sash cables 42 access is readily had to the turnbuckles 40 on either sash when thesame is pivoted inwardly as described; there being nothing on the jambs 45 to prevent access to the turnbuckles 40 on either sash when the'same is pivoted inwardly, as described.

Provided on the sill 56 is an upstanding rail 55. with which a substantially L-shaped flange 57 on the bottom rail 23,.of lower sash 14 is adapted to interlock when the lower sash is in fully lowered position (Fig. 2). Any water formed by condensation on the inner side of the lower sash pane 26 will drain from the bottom rail 23 of the lower sash through drain holes 59 formed at the lower edge of the tapered portion 63 of the bottom rail 17 of the upper sash, down the inclined sill 56, through drainholes 58 in the rail 55; and thence further down the sill 56 to the outside of the window. To drain water formed by condensation on the inner side of the upper sash pane 20 drain holes 60 are provided in a rail 61 that projects upwardly from the lowest edge of the tapered portion 62a of the bottom rail 17 of upper sash 13.

When the upper and lower sashes 13 and 14 are in closed position, Fig. 2, the upper rail 22 of the lower sash and the bottom rail 17 of the upper sash meet in an interlocking wheatheuproof groove and tenon joint 62 lt willbe seen from the foregoing description of the invention that since my improved window structure is an all-metal construction there is nothing such as stop strips to warp or get out of shape; that the interlocking of the arms 28 of the stiles 15 of the upper sash 13 in the vertical jamb grooves 27 and the interlocking of the arms 32 of the stiles 21 of the lower sash 14 in the vertical jamb grooves 31 provide a weatherproof window construction; that both the upper and the lower sash may be pivoted inwardly to clean the same, to place screens, or for any other purpose, making it unnecessary to go outside the window to do these things; and that access may be readily had to the turn buckles 40 on either sash to adjust the tension of the counterbalance cables 42 by pivoting the said sash inwardly as described; and that any water formed by condensation on the inner sides of the sash anes 20 and 26 will drainlto the outside 0 the window as set forth.

While I have illustrated and described the preferred form of construction for carryin my invention into effect, thisis capable o variation and modification, without departing from the' spirit of the invention. I, therefore,'do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is:

1. A window structure comprising a frame including jambs having vertical grooves formed therein, each of said groves having at its lower end a recess and said recesses extending laterally out of said grooves, upper and lower sashes slidable in said frame, members carried by said sashes slidable laterally of said grooves and having portions adapted for projection into and out of said grooves, and certain of said slidable members being adapted to have said projectable portions thereof projected into said recesses.
